"Too hot down there." Yeah, it gets hot in the Summer and early Fall, but I weigh 350lbs, and it doesn't bother me much, as everything is air conditioned and you get used to it. Right now it's about 75 degrees. The "dress code" here is very casual, for the most part, and utilities don't cost an arm & a leg. Property taxes aren't high, either. As for homes, figure on paying about $40-75 per square foot +/-. There are quite a few Federal jobs here, as well as hospitality, gaming, shipbuilding, aerospace, chemicals, retailing, education, medical, etc. 7% sales tax. Military retirees & veterans will like this area (Keesler AFB, Seabee Base in Gulfport, two VA hospitals, etc...)

I never bothered to check the census data on your area because the climate is all I need to know to avoid it--but were I to check it, I have a feeling it would be too populated.
And no offense--but the only house in your last link I clicked on, the first one--is not what I would like any neighborhood I live in to look like.
Can't live in a place without a change of seasons--too monotonous.
And I require a white Christmas.
And one last thing: Not only is it too hot down there now, but it's not likely to get any cooler from global warming.
But I am REAL happy that most people actually like your kind of climate.
Keeps them away from where I'll be moving.
